Set the fabric parameters:
a. At the BB_Credit field, enter a value from 1 through 60 (buffers). The default is 16. Use a
value of 60 (buffers) only for extended distance port operation.
b. At the R_A_TOV field, enter a value from 10 through 1200 tenths of a second (one through
120 seconds). The default is 10 seconds (100 tenths).
All fabric-attached switches must be set to the same R_A_TOV. If the value is not compatible,
the E_Port connection to the switch segments and the switch cannot communicate with the
fabric. In addition, the R_A_TOV must be greater than the E_D_TOV.
c. At the E_D_TOV field, enter a value from 2 through 600 tenths of a second (0.2 through 60
seconds). The default is 20 tenths of a second (2 seconds).
All fabric-attached switches must be set to the same E_D_TOV. If the value is not compatible,
the E_Port connection to the switch segments and the switch cannot communicate with the
fabric. In addition, the E_D_TOV must be less than the R_A_TOV.
d. The switch priority value designates the fabric's principal switch. The principal switch controls
the allocation and distribution of domain IDs for all fabric directors and switches (including
itself). At the Switch Priority field, select Principal, Never Principal, or Default (the default
setting is Default).
e. Select the Interop mode:
• McData Fabric 1.0. (default). Select this mode if the fabric contains only M-Series
switches and switches that are operating in McData Fabric 1.0 mode.
• Open Fabric 1.0. Select this mode if the fabric contains HP directors and switches, as
well as other open-fabric compliant switches. Select this mode for managing
heterogeneous fabrics.
